If the length of each square represents one inch, what is the length from corner B to corner C?
A.
15 inches
B.
12 inches
C.
14 inches
D.
13 inches
===========================================================
Explanation:
There are three methods to solve this problem
--------------------------
Method #1
Let point D be at the location (0,6). So this point is on line BC such that it cuts BC into two pieces of BD and DC.
BD is 7 inches long since it spans from x = -7 to x = 0
DC is also 7 inches long because it spans from x = 0 to x = 7
We can treat everything on line BC as if it was a number line.
So overall, BC = BD+DC = 7+7 = 14 inches
--------------------------
Method #2
Because points B and C are on the same horizontal level, we can subtract the x coordinates of each point. We apply absolute value to ensure the result of subtraction is never negative.
|B-C| = |-7-7| = |-14| = 14
or
|C - B| = |7 - (-7)| = |7 + 7| = |14| = 14
The order of subtraction doesn't matter as long as you use absolute value.
----------------------------
Method #3
We can use the distance formula to compute the distance from B(-7,6) to C(7,6)
So we'll make (x1,y1) = (-7,6) and (x2,y2) = (7,6)
Then we have the following steps
[tex]d = \text{Distance from B to C}\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-7-7)^2 + (6-6)^2}\\\\d = \sqrt{(-14)^2 + (0)^2}\\\\d = \sqrt{196 + 0}\\\\d = \sqrt{196}\\\\d = 14\\\\[/tex]
The distance from B to C is 14 inches, which is the same as saying segment BC is 14 inches long.
The distance formula is overkill in my opinion, so method 1 or 2 might be the better option.

Nathaniel is going to invest $22,000 and leave it in an account for 20 years.
Assuming the interest is compounded continuously, what interest rate, to the nearest
tenth of a percent, would be required in order for Nathaniel to end up with $33,000?
Answer:2.0%
Step-by-step explanation:
The interest rate required to get a total amount of $33,000.00 from compound interest on a principal of $22,000.00 compounded 1 times per year over 20 years is 2.048% per year.
What is the interest rate?r = n[(A/P)1/nt - 1]
r = 1 × [(33,000.00/22,000.00)1/(1)(20) - 1]
r = 0.0204802
Then convert r to R as a percentage
R = r * 100
R = 0.0204802 * 100
R = 2.048%/year
The interest rate required to get a total amount of $33,000.00 from compound interest on a principal of $22,000.00 compounded 1 times per year over 20 years is 2.048% per year.
The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR (APR).To learn more about compound interest refer to:

Answer in table format, picture below
Answer:
x = -0.35
Step-by-step explanation:
tep 1 - Multiply 64 and 0.5x. The answer ends up being 32x
Step 2 - You need to get all of the variables on one side and the regular numbers on the other side. To do that, you need to subtract 2.5x from each side so you are left with the equation -10.5 = 29.5x
Step 3 - The final step is to isolate the variable. To do this, you divide each side by 29.5 meaning that x = -0.35

Answer:
False
Step-by-step explanation:
A set is a collection of objects, things or symbols which are clearly defined. The individual objects in a set are called the members or elements of the set.
All that are related to each other in a way.
For eg: For example, the set of real numbers, the set of even integers, the set of all books written before the year 2000.
Here, in the first all are related as numbers , in second case all are related as books that are before year 2000.

A projectile is fired upward from the ground with an initial velocity of 300 feet per second. Neglecting air resistance, the height of the projectile at any time t can be described by the polynomial function P(t) = 16t 2 + 300t
Answer: The polynomial that describes the projectile's height is:
P(t) = - 16t*2 + 300t
For t = 1 second we have:
P(1) = - 16*1^2 + 300*1
P(1) = 284 ft
The height of the projectile after 1 second is 284 feet.
Step-by-step explanation:
The height should be 284 feet.
Given that,

If you multiply a number by 3 and then add 40, the result is the same as if you add 17 to the number and then multiply by 2. What is the result if you subtract 9 from the number and then multiply by 4? .
Answer:
The number is -6
The second operation is -60
Step-by-step explanation:
Let the number be x.
Solving (a): The value of x
Operations 1:
Multiply by 3: 3x
Add 40: 3x + 40
Operations 2:
Add 17: x + 17
Multiply by 2: (x + 17) * 2
To find x, equate both operations.
[tex]3x + 40 = (x + 17) *2[/tex]
[tex]3x + 40 = 2x + 34[/tex]
Collect like terms
[tex]3x - 2x = 34 - 40[/tex]
[tex]x = -6[/tex]
Solving (b):
Operations:
Subtract 9: [tex]x - 9[/tex]
Multiply by 4: [tex](x - 9) * 4[/tex]
This gives:
[tex](x - 9) * 4 = (-6 - 9) * 4[/tex]
[tex](x - 9) * 4 = -15 * 4[/tex]
[tex](x - 9) * 4 = -60[/tex]

Given the following graph
Find the amplitude and vertical shift?
Please write down the parent function and the function creating the graph.
Answer:
The amplitude = 2b, and the verticle shift = 2, which means it has been shifted down 2 units.
Step-by-step explanation:
The highest point is when y = 0 and the lowest point is when y = -4. The vertical distance between the peak and valley is 4 units, which cuts in half to 2. This is the amplitude. It's the vertical distance from the center to either the peak or valley.

Answer:
So you are given the function, f(x) = 3x - 4. You will plug in the value given and solve and write the answer down in the box.
f(x) = 3x - 4 ---> f(5), f(2), f(1), f(10), and f(-1) value given
f(5) = 3(5) - 4
f(5) = 15 - 4
f(5) = 11
f(2) = 3(2) - 4
f(2) = 6 - 4
f(2) = 2
f(1) = 3(1) - 4
f(1) = 3 - 4
f(1) = -1
f(10) = 3(10) - 4
f(10) = 30 - 4
f(10) = 26
f(-1) = 3(-1) - 4
f(-1) = -3 - 4
f(-1) = -7

Two students are reading a novel. Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts early and is already on page 40
Ashley p=10d
Carly p=8 d+40
On day ___ both girls should be on page___
Answer:
The word per indicates the slope (m) of a linear function, y=mx +b.Using d for x and p for y , the equation representing Ashely's reading is p = 10d. Carly begins on page 40 which represents b, the y intercept of a linear function which indicates an initial amount. So the equation representing Carly's reading is p=8d + 40.
